Unearthing the entangled roots of urban agriculture
2020Jonathan London, Bethany B. Cutts, Kirsten Schwarz, Li Schmidt, Mary L. Cadenasso · Agriculture and Human Values · United States (California)
This study, based on 24 interviews with urban agriculture (UA) leaders in Sacramento, California, identifies three "taproots" of UA projects: justice, health, and market. The analysis reveals how these roots interact differently with racial capitalism, creating disparities in their growth trajectories. Specifically, UA projects associated with the justice taproot are historically underrepresented and undervalued.

2020Tanmoy Roy Tusher, Md. Eusuf Sarker, Sumaya Nasrin, Tapos Kormoker, Ram Proshad, Md. Saiful Islam, Shamim Al Mamun, A. R. M. Tareq · Toxin Reviews · Bangladesh
This study investigated toxic metal and PAH contamination in rooftop soils and vegetables (red amaranth, spinach) in urban and peri-urban Bangladesh. Urban rooftop soil and vegetables were highly contaminated with toxic metals and PAHs compared to peri-urban samples. Lead (Pb) and cadmium (Cd) concentrations in urban vegetables exceeded safe limits. However, health risk indices indicated that the levels of toxic metals and PAHs in urban rooftop vegetables would not pose carcinogenic or non-carcinogenic health risks for adults and children, deeming them safe for consumption.
Contamination & food safetyHealthPeri-urban agriculturePolluted Waters Use in the Urban Agriculture and Its Impact on the Quality of the Grown Vegetables
2020Fabien Ilunga Mpanga, Michel Shengo Lutandula⃰ · The Global Environmental Engineers · Democratic Republic of Congo (Lubumbashi)
A study conducted in the Kasungami district of Lubumbashi, Democratic Republic of Congo, investigated the link between the use of polluted waters in urban agriculture and heavy metal contamination in soil and cultivated vegetables (amaranths, broccolis). Physicochemical and mineral analyses of water, soil, and plant samples revealed that heavy metals, except cobalt, were present in the water used for urban agriculture at concentrations below quality standards, but the soil contained heavy metals at phytotoxic concentrations. Only broccolis were contaminated with lead, while amaranths had heavy metals below quality standards. These findings suggest that urban agriculture in large agglomerations of the DRC could endanger consumers' health.

2020Maëlle Tripon, Dorothée Boccanfuso, Marie-Ève Yergeau · Cahiers de recherche · Global
This literature review examines urban agriculture (UA) models, their implementation contexts, production needs, and impacts. It highlights that UA faces limitations, particularly restricted access to good quality (unpolluted) soil, water, and air, which can negatively impact productivity. UA can also have negative impacts on ecosystems and human health, such as pollution and diseases, depending on management methods.
Contamination & food safetyHealthBiodiversityClimate changeOrganic cycleWho practices urban agriculture? An empirical analysis of participation before and during the COVID‐19 pandemic
2020Lauren Chenarides, Carola Grebitus, Jayson L. Lusk, Iryna Printezis · Agribusiness · United States
This study examined household-level participation in urban agriculture (community and home growing) before (2017) and during (2020 lockdown) the COVID-19 pandemic in Phoenix, AZ, and Detroit, MI, using two online surveys and bivariate probit models. It found that considerably fewer individuals participated in community gardens compared to home gardening, and overall participation was lower in 2020 than in 2017. The continuity of individuals' participation in growing food at community gardens and home is fragile, and many urban households' food-growing practices may not yet be mainstream, suggesting other barriers inhibit participation.

2020Lauren Balotin, Samantha Distler, Antoinette L. Williams, Samuel J. W. Peters, Candis M. Hunter, Chris Theal, Gil Frank, Taranji Alvarado, Rosario Hernandez, Arthur Hines, Eri Saikawa · International Journal of Environmental Research and Public Health · United States (Atlanta)
This study investigated Atlanta residents' knowledge regarding heavy metal and metalloid (HMM) exposures and remediation in urban agriculture, following the detection of industrial slag and hazardous soil contamination in West Atlanta in 2018. Through surveys and follow-up interviews, it was found that participants were concerned about the potential health effects of soil contaminants but unconcerned with produce in their gardens. Gardeners' knowledge of HMM exposure sources and remediation methods was low and varied based on racial group.
Contamination & food safetyHealthCommunityHarvest of the Month for Early Childhood Education: Parent Perspectives
2020Christine Lux, Brianna Routh, Lacy Stephens · Journal of Human Sciences and Extension · United States
This exploratory study surveyed 21 parents from a campus-based preschool in the northwest United States during the 2017-2018 school year to understand the impact of the "Harvest of the Month" program on children's nutrition behavior at home. Findings indicated that a variety of program foods were served and consumed at home, but parents prioritized knowing food origins over serving local foods. Parents' knowledge of farm to ECE, reported farmer's market purchases, and CSA participation were limited, suggesting a need for targeted parent education.

2020Omanjana Goswami, Ashaki A. Rouff · Soil Systems · United States (Newark)
Soils from seven community farms in Newark, New Jersey, USA, were analyzed for lead (Pb) concentration and speciation. Single-step extractable Pb concentration ranged from 22 to 830 mg kg−1, with 21% of samples exceeding the NJDEP limit of 400 mg kg−1 for residential soils. Lowest Pb concentrations were detected in raised beds, while uncultivated native soil and parking lot samples had the highest values. Although most Pb is associated with reducible and oxidizable soil fractions, indicating a lower risk of mobility and bioavailability, Pb exposure through ingestion and inhalation pathways remains a concern when directly handling the soil.
Contamination & food safetyHealthCommunityThe affordable housing, transportation, and food nexus: Community gardens and healthy affordable living in Calgary
2020Miho Lowan‐Trudeau, Noel Keough, Joshua Wong, Sara Haidey · Canadian Geographies / Géographies canadiennes · Canada (Calgary)
This study, examining community gardens in Calgary, aimed to determine the socio-economic demographics of neighborhoods supporting community gardens and their proximity to active transportation and public transit. GIS visualization and quantitative analyses were used to investigate relationships between demographic variables and transportation accessibility. Findings showed that community garden neighborhoods are located in areas with significantly fewer visible minorities, higher levels of educational attainment, and more attached dwellings like apartments and townhomes. This study suggests potential inequities in the proliferation of public community gardens based on socio-economic factors beyond economic capital.
Equity & displacementCommunityHealthWelfareEconomicsA Place to Breathe in the Dense City: Community Gardening and Participatory Urbanism in Paris
2020Carrie Ann Benjamin · Sociální studia / Social Studies · France (Paris)
This study examines community gardening and participatory urbanism in Paris, focusing on the Goutte Verte, a temporary nomadic community garden. The continued existence of the Goutte Verte is in opposition to the city's much-needed housing, with gardeners caught between a desire for green space and a demand for comfortable housing. Community gardens are shown to act as a material alternative to urban planning and governance that often fail to account for a "place to breathe" in the city.

2020Katie L. Butterfield, A. Susana Ramírez · Health Education & Behavior · United States (Minnesota)
A quantitative content analysis was conducted on descriptions, missions, and goals provided by 411 community garden managers across Minnesota. Six frames were consistently present, including "greater good" and "community orientation," which were the most common. The findings suggest that the prevalent "greater good" frame may inadvertently reproduce inequality by alienating food-insecure populations, similar to other alternative food programs.

This article considered the potential risks of contamination in urban agricultural products. Urban agriculture, particularly in large cities, areas with heavy traffic, or near industrial zones, can lead to the accumulation of heavy metals in vegetable crops due to air pollution, traffic pollution, and other sources. Consuming these contaminated fresh vegetables is noted to potentially deteriorate human health.
Contamination & food safetyHealthUrban–rural linkageA systematic, mixed studies review of the outcomes of community garden participation related to food justice
2020Kate Gardner Burt, Gail Mayer, Rachel Paul · Local Environment · Global
A systematic review analyzed 277 community gardening articles to assess outcomes of community garden participation related to food justice, synthesizing 31 studies. Many positive impacts were indicated across seven social and dietary outcomes. Community garden participation was positively correlated with community connectedness, but evidence demonstrating diet improvement was neutral. Methodological rigor in study design and lack of participant racial/ethnic and socioeconomic diversity were common issues, leaving the effectiveness of community gardening as a strategy for a more equitable food system unclear.
